成都市径流污染的概念性模型

概念性模型是根据城市径流形成过程及对水体影响变化的物理机理建立的一套数学模型，模型及参数均有明确的物理意义。本文用概念性模型求出了成都市街道地表物的累积量，降雨径流污染负荷量，并模拟了污染物对受纳水体的影响。

Conceptional Model System of Urban Runoff in Chengdu

The Conceptional Model is a mathematical model which is set up from the process of physical changes.The model and its paramaters have true physical significances.Conceptional Model System of Urban Runoff in Chengdu is a group of concep-tional models on the basis of urban runoff pollution and its impact on the urban waters.With those models,the amount of sediment on the urban streets and the pollution loading of urban runoff are calculated, Finally,the impact on receiving waters(three rivesin Chengdu)is simulated.
